Hackberry (Celtis)

Hackberry Genus Details

Hackberries are grown as shade and boulevard trees and shrubs in metro and rural areas. Trees can reach heights of 60 to 80 feet. Celtis has deciduous leaves that are alternate and simple. The fruit is a drupe, which contains a large seed and a thin, dryish, but sugary flesh (comparable to dates). The leaves of hackberry are similar to those of elms, but they are more pointed than elm leaves, and they are singly toothed along the edges.

Hackberry Allergy Info

Not particularly allergenic, hackberry could cause allergic reactions to those sensitized due to close proximity and continued exposure. Even though Celtis is in the same family as elm, a very allergenic genus, Celtis has not been found to be the source of a great deal of pollinosis.
